MChat Fix

MChatFix is a lightweight client-side Fabric mod for Minecraft 1.21.11 that helps eliminate chat-related lag, stutters, and freezes on multiplayer servers.

In vanilla Minecraft, chat messages are processed on the main game thread. When a message is received or sent, the game briefly pauses to handle that processing, which can cause frame drops or freezes on busy servers.

This is especially noticeable during PvP, combat, crystal fights, and other fast-paced situations where smooth performance matters.

MChatFix moves chat processing to a dedicated background thread, preventing chat activity from interrupting gameplay. As a result, your game stays smoother and more responsive, even when chat is active.

Messages may appear with a tiny delay, but your FPS and gameplay remain consistent.
